 COMPOSITION- ANNEX
 SCOPE
 This
standard prescribes the requirements
and the methods of sampling and test for the
biogas
(biomethane)
applications
in
stationary engines, automotive and thermal
applications and supply through piped
network.
 Biogas
(biomethane) is primarily methane gas
which is generated from an anaerobic
digestion of organic wastes by micro
organisms.
 It has methane as the main component
around 50-70 percent, CO2 around 30-40
percent and H2S and moisture in trace
quantities.
It
varies
in
composition
depending upon the substrates used. It is a
natural product
produced
from
the
biodegradable substrates like cattle dung,
poultry waste, food waste, sewage waste
etc.
 a)
provide the safe operation of the engine
whether stationary or automotive and
associated equipments;
 b) protect the fuel system from the
detrimental effects of corrosion, poisoning
and liquid or solid deposition; and
 c) not emit any pollutants or the greenhouse
gases after combustion, beyond prescribed
limit.
Biogas (biomethane) shall be free from
liquids over the entire range of temperatures
and pressures encountered in the storage and
dispensing system, fuel containers, engine
and fuel system and piped network.
 The biogas (biomethane) fuel shall be free
from particulate matter such as dust, dirt
and mist.

 Biogas
(biomethane) delivered to any
vehicle, stationary engine or piped network,
shall be odorized similar to a level found in
the local distribution

IS 7285 (Part 2). For automotive use, it shall
be filled in cylinders conforming to IS 15490.
 It may be transported through piped network
or injected into existing system of pipelines
as per regulatory requirements.
IS 8749 :2002
Biogas Stove (formulated by
Mechanical
Engg
Department)covers
construction, operation, safety requirements and

Mechanical Engg Department)- specifies the
requirements for contact moulded glass fibre
reinforced polyester resin biogas holders with
steel frame suitable for floating drum type
biogas plants.

Mechanical Engg Department)- sets out minimum
requirements for the material, design, construction
and workmanship, manufacturing processes and tests
at manufacture of refillable quenched and tempered
seamless steel gas cylinders of water capacities from
0.5 litre up to and including 400 litres for
compressed, liquefied and dissolved gases exposed to
extreme worldwide ambient temperatures (normally
between -50 and + 65°C). this part is applicable to
cylinders with a maximum tensile strength Rm of less
than 1 100 MPa (112 kgf/mm2).

FORWARD AGREED DURING MEETING
 Name
of TC255:‘Biogas (anaerobic digestion,
AD)’
 Working scope: ‘Standardization in the field
of biogas in production, utilization and
management in rural, urban and industrial
sectors’.
Proposal Discussed in the meeting - To
formulate international standards in the
following sectors :Household Biogas, Farm
Biogas and Manufacture of Biogas
 i)
Flare for Biogas Plants” specifies
classification of biogas flare, system
structure, technical
performance
requirements, test methods and inspection
instructions, and applies mainly to
biogas hot water boiler with methane flame
burner, the normal production of the
biogas project and the design and quality
control
of emissions of methane gas torch
burner exceptional circumstances, not
including civilian stove and biogas lamps.

Household Biogas Design Specifications- specifies
household biogas digesters in the production
and
construction design. Household biogas as an
important aspect in the application of biogas
technology has been promoted into nearly 40 million
households in China, South-east Asia and Africa as
well as other developing countries where this
technology has been extensively introduced and
employed. Due to the absence of corresponding
international standards, large number of nonstandard situation has been posed in use of national
household biogas, and thus, has resulted in
insufficient performance of household biogas use and
security problems. Therefore, it is necessary to
develop household biogas international standards to
regulate, promote household biogas international
standardization construction.


Reservations about the need for developing Standards for
Household Biogas plants indicating that the Standards for
biogas plants would need to be entirely different for
different countries and even in respective regions of some
of the countries due to differences in ambient
temperatures, feed materials, gas usage, building
materials, and operational regimes, etc.
the Standards for household biogas plants could be kept
out of the purview of the standardization exercise, which
could at the most taken up for developing Standards for
certain components such as biogas stoves, piping and
accessories and not for biogas plants as such. The Chinese
delegation agreed to shelve their proposal and it was
decided that a Drafting Committee consisting of a
representative each from Kenya, France and China would
prepare another note on the subject for inviting comments
from the participating countries before moving further.
